### Description

We present results on the extraction of tensor resonances in the $\eta\pi$ system in a joint analysis between the JPAC and COMPASS collaborations. We use $S$-matrix principles unitarity and analyticity to constrain the reaction model. We find two $J^{PC}=2^{++}$ resonance poles, the $a_2$ and $a_2'$. We discuss extensions of the model to coupled channel systems and the $3\pi$ sector.
